実験手順

To a mixture of (S)-tert-butyl 3-(3-(2-chloro-3-fluorobenzyl)-1-methylureido)-4-(isoquinolin-3-ylcarbamoyloxy)butanoate (0.8 g, 1.47 mmol) and DCM (10 mL) was added TFA (10 mL). The resulting solution was stirred at RT for 1 h. The mixture was concentrated, and the remaining residue was dried in vacuo to give (S)-3-(3-(2-chloro-3-fluorobenzyl)-1-methylureido)-4-(isoquinolin-3-ylcarbamoyloxy)butanoic acid (1.3 g), which was used without further purification. LRMS (M+H+) m/z 489.1.
